Description
Technical field
The invention belongs to feature bean product technical field, and in particular to the soya-bean milk slurries of DHA containing high concentration a kind of, go forward side by side
One step discloses its preparation method, and its for preparing the application of feature bean products.
Background technology
DHA, also known as docosahexaenoic acid, are ω -3 highly unsaturated fatty acids, are commonly called as docosapentaenoic acid, are had to human body
The essential fatty acid of important physiological regulation function, is even more to cause as the essential fatty acid with a variety of physiologically actives in recent years
The extensive concern of people.At present it is known that DHA have promote infant brain development, improve memory, reducing blood lipid, hypotensive,
The effect of the angiocardiopathy such as norcholesterol and prevention coronary heart disease, while can effectively improve brain function, protection retina, changing
It is apt to eyesight, anticancer, treats tracheitis, prevents and treats a variety of physiological functions such as diabetes, anti-aging.In consideration of it, American-European many countries
The intake standard for having formulated daily DHA is 160-400mg/ days, and China is not yet formulated DHA daily recommended intake
Standard.According to statistics, China DHA per capita intake is only 40mg/ days, far below proposed standard of the foreign countries to DHA intakes.
DHA is generally contained in fish oil, and that is extracted from fish and shellfish is relatively more, and this fish oil containing DHA is
The capsule-type healthy food formed as being coated with gelatin etc. is sold.Meanwhile, have attempted to DHA being added to other such as at present
In the general commercial product of beverage, candy, cheese, flavoring etc., it is intended to improve DHA average daily intake in all directions.
However, because DHA itself has long-chain and multiple double bonds, and the distinctive smell as derived from fish oil is produced, so
In many cases, be unsuitable for directly adding DHA in existing food technology, it is necessary to by specific purifying, concentration and
Anti-oxidant treatment can just be added and used.But, in view of difficulty of the DHA on purifying, concentration and anti-oxidation tech so that warp
The fish oil price containing DHA for crossing purifying, emulsification, grinding and the processing such as anti-oxidant is sufficiently expensive.And it will contain DHA's
After fish oil addition or grinding are added in food, DHA stability is unsatisfactorily kept, therefore cannot function as storage food
Product.Therefore, the addition for limiting addition of the DHA fish oil in food, especially high concentration DHA is even more very difficult.
It recent studies have shown that, soybean contains the protein with high essential amino acids content and excellent body absorption,
It can improve DHA as the linoleic acid of n-6 highly unsaturated fatty acids and the active functional materials with reduction cholesterol
Emulsibility.Moreover, having developed addition finite concentration DHA bean product (such as bean curd or soyabean milk beverage), it is good for as traditional
Health food is eaten and drunk daily so that infrequently the people of food fish can absorb DHA naturally from dairy products or beverage,
So as to maintain or be lifted its health status.But, presently disclosed soya-bean milk or bean product scheme containing DHA are still only applicable to
The DHA additions of low concentration, for high concentration DHA, then occur that layering or fishlike smell are overweight rather than for edible
Problem.
The content of the invention
Therefore, the technical problems to be solved by the invention are the soya-bean milk slurries for providing a kind of DHA containing high concentration, one is gone forward side by side
The open its preparation method of step.
It is used for the purposes for preparing the feature bean products of DHA containing high concentration the invention also discloses the soya-bean milk slurries.
In order to solve the above technical problems, a kind of DHA containing high concentration of the present invention soya-bean milk slurries, including soya-bean milk and contain
DHA fish oil, the mass content that the fish oil containing DHA accounts for the soya-bean milk is 2-20wt%.
The mass content that the fish oil containing DHA accounts for the soya-bean milk is 10-20wt%.
DHA content is 20-30wt% in the fish oil.
The soya-bean milk adds water for soybean grinds and removes gained slurries after filter residue, and the solid-liquid ratio of the soybean and water is 1：4-
5。
The invention also discloses a kind of method for the soya-bean milk slurries for preparing the described DHA containing high concentration, comprise the following steps：
(1) take part soya-bean milk to be mixed with a selected amount of fish oil containing DHA, obtain emulsion form fish oil；
(2) by the emulsion form fish oil in carrying out freezing processing under cryogenic conditions, then by the emulsion form after freezing processing
Fish oil carries out ice-melt processing, and circulates above-mentioned freezing and the step of ice-melt is handled, obtain the emulsion form fish oil after modification；
(3) remaining heating soybean milk is taken to 90-100 DEG C, and is mixed with emulsion form fish oil homogeneous after the modification, is produced
The soya-bean milk slurries of the DHA containing high concentration.
In the step (1), the mass ratio of the soya-bean milk and the fish oil containing DHA is 1：0.2-1.
In the step (2), the emulsion form fish oil freezing processing step control temperature be -4~0 DEG C, the emulsion
Shape fish oil ice-melt process step control temperature be 15~20 DEG C.
In the step (2), the cycle-index of the emulsion form fish oil freezing and ice-melt step is 2-3 times.
Contain high concentration the invention also discloses what the soya-bean milk slurries or methods described of the DHA containing high concentration were prepared
DHA soya-bean milk slurries are used for the purposes for preparing feature bean products.
The invention also discloses a kind of feature bean products, by the soya-bean milk slurries or described of the DHA containing high concentration
The soya-bean milk slurries for the DHA containing high concentration that method is prepared are made through conventional method.
The feature bean products include soyabean milk beverage, bean curd or bean powder.
Soya-bean milk slurries of the present invention are by the way that emulsion form fish oil is modified the side of processing to obtained by preparation process
Formula, effectively improves the performance of its water and oil balance, and further improves coverage effect of the soya-bean milk to fish oil peculiar smell so that high
What the DHA fish oil of concentration can be stablized be present in soya-bean milk, and and then be made the feature bean products that other high DHA need.
Soya-bean milk slurries of the present invention, in preparation process, the emulsification of identical DHA fish oil is used as using soya-bean milk material
Agent is used, and is diluted to predetermined DHA concentration using soya-bean milk, meanwhile, soya-bean milk is used as emulsifying agent, can effectively be sheltered containing one
Determine the distinctive fish oil peculiar smell of DHA fish oil of low concentration, the cost of scattered emulsifying agent is not only eliminated, while preparation technology is more
It is simple and practical.
